determining the construction of product, co-operation of its component parts and explaining
principle of work of product.
Overall Drawing is a document, containing the contour (simplified) view of product with
overall, locational and joinings sizes.
Circuit is a document on which component parts of product and connection between them are
rotined as conventional images or denotations . Text designer documents are documents, containing
information about product as texts which can be presented in form tables, lists etc. To the text
designer documents behave, in particular:
SPECIFICATION (document, determining composition of assembly unit, complex or
complete set);
Technical regulation (document, containing requirements to product, its making, control,
formal acceptance and delivery, which beside the purpose to specify in other documents), and also
different LISTS, TABLES, etc. using for development, in a production, exploitation and repair of
products.
State Standard 2.103 – 68 divided designer documents into design and detail depending on the
stages of development.
Preliminary design and contract design belong to design project. The incoming in a technical
project drafts of general views are contained by basic data for implementation of detail documents -
specification, assembly drawing, detail design etc. Concordantly State Standard 2.103 - 68 the
followings stages of development of designer document are set:
1. Draft proposalis an aggregate of designer documents, containing the analysis of different
variants of possible decisions of requirement specification of customer, feasability studies of the
offered variants, patent search etc.
2. Preliminary design is an aggregate of designer documents, which must plug in itself of
principle structural decisions, givings the general picture of device and principle of work of product,
and also information, determining setting, basic parameters and overall sizes of the developed
product.
3. Contract design - aggregate of designer documents, which must contain final technical
decisions, givings the complete picture of device of the developed product and basic data for
development of working document. A technical project serves as foundation for development of
detail designer document.
4. Detail designer documents is an aggregate of designer documents, intended for making and
tests of pre-production model, adjusting party, serial (mass) production of products.

QUESTIONS FOR SELFCHECK

1. What types of standards do you know?
2. What product is?
3. What detail is?
4. What complex is?
